Description

Technical Field

[0001] This utility model relates to the field of stamping equipment technology, and in particular to a stamping equipment for processing automotive parts. Background Technology

[0002] Stamping technology is a widely used forming process in the manufacturing of automotive parts, mainly used to produce sheet metal structural parts.

[0003] A search revealed Chinese patent CN211101165U, which discloses a stamping device for processing automotive parts. The device includes a base, a fixed seat fixedly connected to the upper end of the base, an upper base plate on the upper side of the fixed seat, a pair of telescopic rods connected between the upper base plate and the base, a fixed groove carved at the upper end of the fixed seat, a lower die placed in the fixed groove, and a pair of fixed blocks fixedly connected to both ends of the fixed seat. Adjusting bolts are threaded onto the fixed blocks. This device allows for convenient replacement of the stamping head and stamping die, facilitating the processing of workpieces of different specifications.

[0004] However, the device still has the following problems: when changing the mold, the operator needs to manually turn a pair of adjusting bolts to disengage the clamping plate from the lower mold, and then replace it with a lower mold of another specification. In the opposite direction, the pair of adjusting bolts are turned to clamp and fix the lower mold with a pair of clamping plates. The operation is cumbersome and it is difficult to effectively improve the efficiency of changing the lower mold. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a stamping device for processing automotive parts.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A stamping device for processing automotive parts includes a base plate, with support columns fixedly connected to the top corners of the base plate, and a support plate fixedly connected to the tops of two pairs of support columns. It also includes a fastening assembly and a stamping assembly disposed below the support plate.

[0007] The fastening assembly includes a base fixedly connected to the top of a base plate. A fixing frame is fixedly connected to the top of the base plate near the base. A lead screw is rotatably connected to one end of the fixing frame, and a slider is slidably connected to one end of the lead screw. A groove adapted to the slider is provided on the top of the fixing frame. A pair of fixing blocks are fixedly connected to the top of the base plate near the fixing frame. A worm gear is rotatably connected to one end of the pair of fixing blocks. A worm wheel meshing with the worm gear is fixedly connected to the other end of the lead screw. The helix angle between the worm wheel and the worm gear is less than the friction angle. The worm wheel and worm gear transmission has a self-locking characteristic, which can prevent the clamping force from loosening during the stamping process, ensure the stable fixation of the workpiece, and improve the processing accuracy and safety.

[0008] One end of the slider is fixedly connected to a connecting rod, and both ends of the connecting rod are fixedly connected to a pair of guide blocks. Both sides of the inner wall of the base are fixedly connected to a pair of guide rods. Both ends of each guide rod are slidably connected to a connecting block. The top of each pair of connecting blocks is fixedly connected to a sliding frame. The bottom of each sliding frame is provided with a guide groove three that matches the guide block. The guide groove three is inclined along the diagonal of the bottom of the sliding frame. The inclined guide groove three cooperates with the guide block to convert the linear motion of the lead screw into the opposite or opposite motion of the sliding frame, realizing bidirectional synchronous clamping or loosening, with strong consistency of action and avoiding unilateral load.

[0009] Preferably, each guide block is cylindrical, and a pair of guide grooves adapted to the guide blocks are provided on both sides of the top of the base. Two pairs of guide grooves adapted to the connecting blocks are provided on the top of the base near the guide rod. The cylindrical guide blocks cooperate with the guide grooves to reduce motion friction and improve transmission efficiency and service life.

[0010] Preferably, a bidirectional motor is fixedly connected to the top of the base plate near the fixing block, and the output shaft of the bidirectional motor is fixedly connected to one end of the worm gear.

[0011] Preferably, one end of the pair of sliding frames is jointly engaged with the lower mold, and the inner wall of each sliding frame is fixedly connected with a buffer pad. The buffer pad can absorb the vibration and impact during the stamping process, protect the mold and the workpiece, and reduce noise and wear.

[0012] Preferably, the stamping assembly includes a hydraulic telescopic rod fixedly connected to one end of the support plate, and the extended end of the hydraulic telescopic rod is fixedly connected to a mounting plate.

[0013] Preferably, the top of the mounting plate is threaded with two pairs of fastening bolts, and one end of the two pairs of fastening bolts is threadedly connected to the upper mold.

[0014] The beneficial effects of this utility model are as follows: 1. The slider is driven by the lead screw to move along the slide groove direction. Then, the slider drives the connecting rod and the guide block to move along the second direction of the guide groove. Then, through the mutual cooperation between the guide block and the third guide groove, the sliding frame is driven to move along the first direction of the guide groove, so that a pair of sliding frames move closer to each other. Through the mutual cooperation between the pair of sliding frames and the buffer pad, the lower mold is clamped and fixed, which effectively improves the efficiency of the device in changing the lower mold. 2. The self-locking effect between the worm gear and the worm prevents the sliding frame from shifting due to external forces, thus preventing the clamping force from loosening during the stamping process, ensuring the workpiece is stably fixed, and improving processing accuracy and safety.
